In sintesi

The avalanche danger on the Skyline is HIGH today.

Avalanches are breaking both within the newer snow as well as deeper into loose sugary facets.

Natural avalanches are not expected but human triggered avalanches are very likely.

Continue to avoid all steep wind loaded slopes, especially those slopes facing northeast, east and southeast.

    Two distinct avalanche patterns emerged from all the activity reported Sunday. The first involves newer wind drifted snow. There is a weakness just above the stout melt-freeze crust from the February warm up. Avalanches are breaking 1 to 2 feet deep. Most of the activity has been on more east facing slopes but I did spot one slide that ran on a south facing slope.

    The other pattern is avalanches breaking deeper into older sugary faceted snow. These are not as likely but the consequences are more severe. Again, east facing terrain is more dangerous because those slopes have been wind loaded. However, the facets are everywhere and all steep slopes should be avoided.

Recent Activity

There's been lot's of avalanche activity to report. There were natural avalanches during the storm and human triggered avalanches on Sunday.

Snowmobilers triggered a sizeable pocket in Six Mile Canyon. This one did not break deep into facets. No one was caught.

Snowcat grooming on N Skyline triggered a small but deep pocket. This one failed in old facets.

Snow and Weather

Current Conditions: The Skyline picked up a couple of inches of snow since Sunday. The wind from the west did not get nearly as strong as I anticipated but strong enough to transport snow. Temperatures reached around 30˚F Sunday and cooled into the mid 20s overnight. Riding conditions are slowly getting better but it's still kind of "hit or miss". More current condition info can be found in these two backcountry observations:

Chris Magerl, Electric Lake zone

Brett Kobernik, Rolfson & Ephraim Canyon

Mountain Weather: We're going to see mostly cloudy skies today with the chance of snow. Another impulse moves through later on and into Tuesday that could bring 2 to 4 inches of new snow. Wind will remain from the west in the moderate speed category. Temperatures will get up around 30˚F again. There's another system that will move through on Thursday bringing another chance for a few inches of new snow.
